Lose - lose is if he pulls out. He doesn't get a shitton by winning but he loses the reputation he's been building for the past three years of a company man who'll throw down against anybody anytime. Once you lose that, it's gone, every Conor hater will have an argument (however topic-irrelevant) to throw against him. You think it was bad when Jon Jones pulled out against Sonnen? This would go nuclear... so no, he should not have pulled out. He's gotta beat Nate.
